Siren 3 Plus and sensors thoughts
I recently upgraded to the Siren 3 Plus. This is my third monitoring system from Siren, and I am pleased. I would have preferred more wired inputs for temperature and bilge, but you can use other inputs like security for something for a bilge. If you are interested in more wired inputs, I would suggest using the Siren 3 Pro.
The wireless sensors are nice, but I would prefer to not have to change a battery, especially in hard to reach places. Looking forward to Siren enabling a wired power source to a wireless sensor to eliminate the battery replacement issue. This would be particularly easy for a battery monitoring sensor, but Siren would probably have add an additional wire for a bilge sensor.
